According to IUPAC nomenclature, what is the three-letter temporary symbol for the element with atomic number 120 ?

Options

  1. AUnb
  2. BUbn
  3. CUun
  4. DUbb

Correct answer

B. Ubn

Step-by-step solution

The atomic number of the element is 120 . According to IUPAC systematic nomenclature, the roots for the digits are: 1 un 2 bi 0 nil Combining these roots, the temporary IUPAC name for the element is unbinilium. The three-letter temporary symbol is derived from the first letters of these roots, which gives Ubn. Answer: Ubn
